Ezekiel 1:7
5 In the fire were what looked like four living beings. In their appearance they had human form, 6 but each had four faces and four wings. 7 Their legs were straight, but the soles of their feet were like calves’ feet. They gleamed like polished bronze. 8 They had human hands under their wings on their four sides. As for the faces and wings of the four of them, 9 their wings touched each other; they did not turn as they moved, but went straight ahead.
LXX Ezekiel 1:7
5 And in the midst as it were the likeness of four living creatures. And this was their appearance; the likeness of a man was upon them. 6 And each one had four faces, and each one had four wings. 7 And their legs were straight; and their feet were winged, and there were sparks, like gleaming brass, and their wings were light. 8 And the hand of a man was under their wings on their four sides. 9 And the faces of them four turned not when they went; they went every one straight forward.
